Abstract :The results of this study show a mutagenic effect of low-dose ionizing radiation in male germ cells. The damage of male germ cells was assessed by the frequency of abnormal sperm heads in tundra voles insert ignore into journalissuearticles values(Microtus oeconomus Pall.);, bank voles insert ignore into journalissuearticles values(Myodes glareolus Schreb.);, and field mice insert ignore into journalissuearticles values(Apodemus agrarius Pall.); from the 30 km exclusion zone around the Chernobyl nuclear power station and for laboratory animals insert ignore into journalissuearticles values(mice and rats); under chronic γ-irradiation. The abnormal sperm head detection method used appeared to be sensitive to conditions of low-dose irradiation and can consequently be recommended as a bioindicator to monitor environmental radiation pollution.
Keywords : Abnormal sperm heads, long term irradiation, low dose rate, small mammals
